Experiment device for research magnetic equipotential lines

This invention relates to an experimental installation of studying magnetic equipotential lines. The invention mainly includes: a downside base (1); the X-axis carriage (2) installed on the said downside base (1); the X-axis shaking handle (3) installed on the said X-axis carriage (2) and intermediate cross-linked; the Y-axis carriage (4) installed on the said X-axis carriage (2) connected from the upside; the Y-axis shaking handle (5) installed on the said Y-axis carriage (4) and intermediate cross-linked; the circular plate (6) installed on the said Y-axis carriage (4) connected from the upside; the said circular plate (6) connected with the same circular plate handle (10); the arc-shaped plastic hoses (7) installed on the said downside base (1); the magnetic probe (8) installed on the top of the said plastic hoses (7); the magnetic lines indication box (9) installed on the said circular plate (6). The invention is simple structure, easy to use, clear to express and observe the magnetic equipotential lines, so it can provide the university and high school students for the magnetic properties research study.
